Definitions
- This invention relates to a method for fabricating a solenoid device for electromagnetic valves, and more particularly to a method for fabricating a molded solenoid device which is encased in a molded synthetic resin shell.
- the solenoid devices which are widely used for electromagnetic valves are largely constituted by a solenoid coil wound on a bobbin of a non-magnetic material, a couple of rod-like coil terminals projected outwardly from the bobbin and connected to the head and tail ends of the winding wire of the solenoid coil, a fixed iron core fixedly mounted in an iron core chamber coaxially at the center of the bobbin, a magnetic frame of a magnetic material located to circumvent the afore-mentioned component parts, and a movable iron core disposed movably within the iron core chamber, the circumference of the magnetic frame being embedded in an insulating synthetic resin material by molding.
- the mold In order to mold the solenoid device with an insulating synthetic resin, it has been the general practice to place, within a mold cavity, a solenoid assembly except the movable iron core, and to introduce a molten synthetic resin material into the mold cavity around the solenoid assembly.
- a solenoid assembly In order to mold the solenoid assembly with an insulating synthetic resin, it has been the general practice to place, within a mold cavity, a solenoid assembly except the movable iron core, and to introduce a molten synthetic resin material into the mold cavity around the solenoid assembly.
- the mold is usually provided with a couple of coil terminal escape holes in which the respective coil terminals are fitted when the solenoid assembly is set in molding position in the mold cavity.
- the above-mentioned sealing cover members are each formed in a tubular shape with a tapered circumferential surface from an intermediate portion toward one end to be located on the outer side when fitted on the terminal coils, so that they snugly fit into the coil terminal escape holes and tightly held in abutting engagement with inner edge portions of the latter.
- FIG. 1 is a sectional view of an electromagnetic valve incorporating a molded solenoid device fabricated by the method of the present invention
- FIG. 2 is a sectional view of a solenoid assembly, explanatory of the steps of assembling solenoid device according to the method of the invention.
- FIG. 3 is a sectional view explanatory of the method of molding the solenoid device with an insulating synthetic resin material.
- FIG. 1 Illustrated in FIG. 1 is an electromagnetic valve incorporating a solenoid device 1 fabricated by the method of the present invention.
- This electromagnetic valve is composed of a valve section 2 including an inlet port P and an outlet port A for pressurized fluid like compressed air, and a valve seat 31 provided in a fluid passage intercommunicating the inlet port P and the outlet port A, a solenoid device 1 mounted on a casing 30 of the valve section 2, and an electrical wiring section 3 mounted on top of the upper end of the solenoid device 1.
- the reference 20 indicates a return spring biasing the movable iron core 17 in the closing direction or in the direction toward the valve seat 31.
- the electrical wiring section 3 includes a printed wiring board 41 which is housed in a cover 40 and electrically connected to the above-mentioned coil terminals 11 and to a power supply terminal 42, the printed wiring board 41 supporting thereon various electrical parts including an indicator, resistors, counter electromotive force inhibitor and so forth although they are omitted in the drawing for the sake of simplicity of illustration.
- the movable iron core 17 upon supplying current to the coil 12 of the solenoid device 1 through the power supply terminal 42, the movable iron core 17 is electromagnetically attracted by the fixed iron core 15. As a result, the valve seat 31 is opened, permitting the pressurized fluid to flow from the inlet port P to the outlet port A. As soon as the power supply is cut off, the movable iron core 17 is returned to the position of FIG. 1 under the influence of the biasing action of the return spring 20, closing the valve seat 31 to block the flow of the pressurized fluid.
- the solenoid device 1 is fabricated through the following steps. As seen in FIG. 2, firstly a couple of coil terminals 11 are fixedly fitted in terminal anchor holes 22 which are provided on one flange 10b of the bobbin 10. Nextly, the leading or head end of a winding wire 12a is led out through a groove 24 on the flange 10b, and soldered to one coil terminal 11 after being entwined around the latter several times.
- the wire 10b is wound on the cylindrical body portion 10a of the bobbin 10 to form a solenoid coil of a required number of turns, and the tail end of the winding wire 10b is led out through a groove 25 on the flange 10b and soldered to the other coil terminal 11 after being entwined around the latter several times.
- resilient sealing cover members 13 of an electrically insulating material like rubber or synthetic resin material, are fitted on base end portions of the coil terminals 11 in such a manner as to cover the connected ends of the winding wire 12a.
- Each of the sealing cover members 13 is formed in a short tubular shape having its outer periphery tapered toward one end to be located on the outer side when fitted on the coil terminal 11.
- the fixed iron core 15 is fixedly mounted in the iron core chamber 14 within the cylindrical body portion 10a of the bobbin 10, and the magnetic frame 16 is fixed around the circumference of the bobbin 10.
- the magnetic frame 16 is provided with radial inlet openings 23 at suitable positions to let the molding synthetic resin 19 enter and fill in the internal space of the magnetic frame 16.
- the solenoid assembly which has been assembled through the above-described steps is then set in split mold members 50a and 50b, in such a way that the coil terminals 11 are fitted in a couple of coil terminal escape holes 51 as shown in FIG. 3, with the tapered portions 13a of the respective sealing cover members 13 held in abutting engagement with the inner edges of the latter to form seals around the coil terminals 11 in the respective escape holes 51.
- One mold member 50a is provided with an abutting wall portion 52 to be held in engagement with the top surface of the magnetic frame 16, while the other mold member 50b is provided with abutting wall portion 53 to be fitted into the iron core chamber 14 for engagement with the electromagnetically attracting surface of the fixed iron core 15 and an abutting wall portion 54 to be held in abutting engagement with the bottom surface of the magnetic frame 16.
- the two mold members 50a and 50b are closed on one another, fitting the abutting portion 53 of the mold member 50b into the iron core chamber 14.
- the solenoid assembly Upon closing the two mold members 50a and 50b, the solenoid assembly is retained in position within the mold by the above-mentioned abutting wall portions 52, 53 and 54, and the tapered circumferences 13a of the sealing cover members 13 are tightly abutted against the inner marginal edges of the terminal escape holes 51 in a wedge-like fashion.
- molten synthetic resin material 19 is introduced into the mold cavity 55 around the solenoid assembly within the closed mold members 50a and 50b to mold the solenoid assembly.
- the sealing cover members 13 are embedded in the synthetic resin material 19 except their outer end portions which are partly exposed to the outside.
- the synthetic resin material 19 which has been introduced into the mold cavity has no possibility of leaking to the outside through the terminal escape holes 15 since the tapered portions 13a of the sealing cover members 13 are tightly abutted against the inner edge portions of the escape holes 15 as described hereinbefore.
- the coil terminals 11 are kept from direct contact with inner edge portions 51a of the terminal escape holes 51, precluding the possibilities of damages to the coil terminals 11 or breakage of the coil winding 12a.
- the mold members 50a and 50b are opened to eject the molded solenoid assembly, which is encased in the plastic insulation shell, and the movable iron core 17 is mounted in the iron core chamber 14 of the molded solenoid assembly to complete a solenoid device 1.
